Rightfully so, Western digital has entirely won me over as a customer, ten fold even. Here's my story, which I plan on inputting in a few places. (amazon.com, ebay, etc.)
I bought a 400 gig hard drive on ebay from a reputable power seller. (the only way to go.) I paid $90 bucks, and got the internal hard drive installed. It wasn't working. I went to the western digital site and walked through a few different trouble shooting processes, and downloaded testing software. Long story short, I fill out a return form and send off my hard drive. It took them about 3 weeks, but I got a replacement hard drive back factory direct. I thought it was nice that they would even exchange a faulty hard drive, considering the source of which I made purchase. I get the hard drive, and to my utter amazement, the hard drive is a 750 gigger. Wow. Thank you so much, Western Digital, for bumping my order up. I'm not sure what I did to deserve that, maybe my hard drive's model was old, but having 350 gigs more than I started out with was a sweet suprise. I'm a Western Digital HD fan for life. Since then, I've gotten another hard drive, and will recommend that brand to everyone I help out. (I'm probably going to reapply to work at Best Buy again.)
So, do yourself a favor and buy WD.
